ada102456d Auto merge of #84614 - RalfJung:daily, r=Mark-Simulacrum 
don't enable parking_lot nightly features

Having the compiler itself depend on external libraries that use nightly features can lead to "fun" bootstrap situations. Within the rustc repo we use `cfg(bootstrap)` to resolve those, but that is not a reasonable option for external dependencies.

So I propose we stop enabling the "nightly" feature of `parking_lot` here. In my experiments, this then indeed leads to the feature not being enabled (i.e., nothing else enables it), and everything still builds. However, this means parking_lot's `RwLock` will no longer have hardware lock elision for readers -- I hope that is okay to lose in exchange for less bootstrap brain twisting. ;)

e8eb691c1f Use arrayvec 0.7, drop smallvec 0.6 
With the arrival of min const generics, many alt-vec libraries have
updated to use it in some way and arrayvec is no exception. Use the
latest with minor refactoring.

Also, rustc_workspace_hack is the only user of smallvec 0.6 in the
entire tree, so drop it.

8331dbe6d0 Add an Mmap wrapper to rustc_data_structures 
This wrapper implements StableAddress and falls back to directly reading
the file on wasm32

f7e75a2124 Update to rustc-rayon 0.3.1 
This pulls in rust-lang/rustc-rayon#8 to fix #81425. (h/t @ammaraskar)

That revealed weak constraints on `rustc_arena::DropArena`, because its
`DropType` was holding type-erased raw pointers to generic `T`. We can
implement `Send` for `DropType` (under `cfg(parallel_compiler)`) by
requiring all `T: Send` before they're type-erased.

e130e9cf77 Update measureme dependency to the latest version 
This version adds the ability to use `rdpmc` hardware-based performance
counters instead of wall-clock time for measuring duration. This also
introduces a dependency on the `perf-event-open-sys` crate on Linux
which is used when using hardware counters.

6d3acf5129 Auto merge of #76928 - lcnr:opaque-types-cache, r=tmandry 
cache types during normalization

partially fixes #75992

reduces the following test from 14 to 3 seconds locally.

cc `@Mark-Simulacrum` would it make sense to add that test to `perf`?
